All releases of fio

Release Notes: A sync engine fix for Windows, support for the Ceph rados block device and Gluster IO engine, improvements to the replay of iologs or blktrace files, support for ARM 64, improvements for S390, and parallellized writeout of IO logs, making that part much faster. There were lots of other bugfixes and improvements.

Release Notes: Full support for IPv6 for the net I/O engine. Windows threading fixes. Support for ranges in the 'startdelay' option. Adds rbd (rados block device) engine support. Various fixes for blktrace playback on Linux. Adds OpenBSD support. An option added to manually seed random generators. Various client/server fixes. A fix for a crash on some file locking options. Adds support for fast software-based xxhash, and support for testing checksum speeds. A fix for not always honoring the 'openfiles' setting. Support for setting policy on how to distribute CPUs set for jobs. Support for data retention testing with verify.

Release Notes: Adds JSON output for client/server. A fix for Windows build breakage in the previous release. A fix for ioengine specific options. Adds support for O_ATOMIC atomic writes on Linux. A failsafe check for realloc() failure during logging. A fix for a Solaris thread problem. Various man page and documentation updates. A fix for a crash on PowerPC without the mfspr instruction.

Release Notes: This release adds basic support for an ACT (aerospike) profile,
fixes atomic write support,
adds various parsing fixes,
makes a big revamp of the included graphing support,
makes the IOPS log includes bandwidth,
adds support for specific randomness settings for both reads and writes,
adds support for random vs. sequential blocksize settings,
fixes a potential verification failure,
and adds multicast support for the net ioengine.

Release Notes: This release adds an --eta-newline option to insert ETA new line at fixed intervals. Fixes for the CPU clock, notably PPC. Fixes for workloads with read/write file locking. A fix for skewed latencies with rated IOPS. Fixes a bug with block sizes varying more than 64x. Improves the LFSR implementation. Fixes missing JSON bandwidth output. Various fixes for the Android platform. Uses ginstall on Solaris. Fixes man page installation. Other bugfixes and improvements.

Release Notes: Autodetect features with a new configure script when building. Improve ETA for some workloads. Support for verify mode that requires no metadata, greatly reducing memory requirements for big device verify workloads. Ensures fsync is always done, even for direct/raw I/O (if asked to). Support for unified read/write/trim reporting. A few axmap and cpuclock bugfixes. Fixes zones and numjobs used together. Adds support for idle profiling, showing idle system CPU when running a workload. Various Windows fixes. FreeBSD now supports CPU affinities. Many other fixes; all users should upgrade.

Release Notes: A few build issues were fixed on a few select platforms, where issues with CC override or missing CPU clock support would break compilation. Setting of size= for zipf/pareto workloads was fixed. Floating math for CPU clock was sped up and improved, further reducing overhead. A potential null pointer dereference on IO verification and requeue events was fixed.

Release Notes: Android platform support was added. Memory consumption on Windows when using many files was reduced. Support for non-uniform random IO was added, using pareto/zipf distributions. A faster LFSR random generator was provided. Various fixes and improvements were made in the network engine. Ping-pong network IO is now supported. The default clock was sped up, and accuracy of the CPU clock was improved. A potential bi-modal performance issue on Linux with multiple processes and O_DIRECT was fixed. A timekeeping race bug with threads was fixed. NUMA job and memory control options were added. A bug in the CPU load engine was fixed. There were various other fixes and improvements.
